Sig Sauer Foxtrot 2R FAQs
What kind of battery does the FOXTROT2R Light use?
The Sig Sauer FOXTROT2 gives you two power choices. You can use the rechargeable 16340 battery that comes in the box. Or, you can use a common CR123A battery as a backup. This means you will always have a way to power your light.

Will the FOXTROT2R fit my handgun?
It is made to fit a wide range of handguns with accessory rails. The box includes two different rail inserts to help you get a secure fit. One is for standard MIL-STD 1913 rails, and the other is for pistols with non-standard rails. It fits all compact and full-size SIG SAUER pistols that have an accessory rail.
How bright is this light?
This light is very bright and focused. It has an output of 700 lumens, which measures the total amount of light. It also has a rating of 20,000 candela, which means the light is concentrated into a tight, intense beam. This powerful beam helps you see things clearly from far away.
How do I turn the light on and off?
You use the paddles located on both sides of the light. You can program the light to work in one of three modes. Momentary mode keeps the light on only while you are pressing the paddle. Latching mode turns the light on with a quick press and stays on until you press it again.

Is the FOXTROT2R durable and waterproof?
Yes. The body is made from strong 6061 aluminum to handle rough use. It has an IPX7 waterproof rating, which means it can be in 1 meter of water for up to 30 minutes and still work perfectly.
What is the correct name for this product?
The official name of the product is Sig Sauer FOXTROT2R. You will also see it called FOXTROT2R or Sig FOXTROT2R, and these are also correct.
While you might see other names used online, the following terms are not official product names:
- SOF2R100: This is the product's SKU number, which is a code used by stores for inventory and ordering.
- FOXTROT 2, FOXTROT2 Light, Sig FOXTROT 2, Sig Sauer FOXTROT 2, and FOXTROT 2 light: These names are missing the "R". The "R" is important because it refers to the model with the rechargeable and FlexCore™ dual-power features.
- FOXTROT 2R light, FOXTROT 2R tactical light, and FOXTROT 2R weapon light: These are descriptions that tell you what the product is (a tactical weapon light), but they are not the official model name.
